Security is required almost every product regular electrical safety tester to check voltage rise but insulation products, is an important part of the periodic safety of electrical products stand up to check for insulation breakdown. Dielectric strength, the distance and space insulating material to withstand the check is a test to determine by providing a voltage exceeding the rated voltage towards the equipment for a period of time, whether standards happens to be, it is a so-called high-voltage test.
Please confirm that you know how to
One. I will check whether it is "OFF" the main power switch is a high-pot tester.
2. Except for the special design of the equipment, other conductive metal parts of all, you need to ground really well.
3. Connect the cables and all the energy input at the end of the instrument.
4. Close and all power switches and relays
5. Set the test voltage hi-pot tester to zero.
6. I connect to (in most cases red) high-voltage transmission lines to the power input terminal of the instrument.
7. Connect the (quite often black) ground wire to a metal part of the conductive loop accessible measurement equipment.
8. Close the energy switch in one of the most hi-pot tester, gradually increasing the secondary voltage of the high-pot tester to the desired value. In general, the rate of increase in the voltage should be kept below 500V/sec.
9. This test voltage is maintained within the specified time.
10. I gradually lower the test voltage.
11. Remove the power change in one of the most hi-pot tester. Ground wire loop to cut the high-voltage transmission lines from the first.
Shows that the measurement device has failed the test the following cases:
I can not test voltage is raised or lowered instead toward the desired voltage value.
There is a warning signal to the hi-pot tester.
Since there may happen to be a danger to the human body that is present in the pressure test voltage of dielectric, High Voltage Testing Set, and we must be noticed that care must be taken really pretty.
If you are able to free the instrument from the factory dielectric voltage withstand the check.
Energy input in the product, the output is SELV ELV or the secondary side of the transformer and other products such as energy supply. Insulating Oil Testers
The items, use the supply of alternative energy, such as a component, when complete, from the input and output connectors, this power is identified by the CSA. Sada case identification, it is this power has passed to endure the isolation voltage check by CSA. You can be there, because it considered to mitigate the rise in the dielectric withstand test. Nevertheless, we have to check whether or not the power supply is damaged before it is actually installed.
Signal is applied to the transformer in the circuit of the same voltage, if it is not really a safety device, we can consider mitigate core component of dielectric strength to stand up to check from the beginning.
Some of the questions that you need to pay special attention to:
H V Testing Set
You must specify personnel that have been trained and certified it just came to the test zone, to be able to operate the equipment.
Warning signal to a fixed eye-catching should be set around the check zone to keep others from hazardous areas far.
During the test, all personnel, including the operator, it is necessary to keep the distance between the measuring equipment and hi-pot tester.
Tester is started, the output line everyone please do not touch.
